Absolute Maximum Ratings
Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All
voltage parameters are absolute voltages referenced to COM lead. Stresses beyond those listed under "
Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only; and
functional operation of the device at these or any other condition beyond those indicated in the
“Recommended Operating Conditions” is not implied. Exposure to absolute-maximum-rated conditions for
extended periods may affect device reliability. The thermal resistance and power dissipation ratings are
measured under board mounted and still air conditions. Ambient temperature (T
A
) is 25°C, unless otherwise
specified.
